The eccentricity and self-aligning of the bearing seat is not a mean
No, the eccentric of the bearing seat belongs to the installation defect. When there is eccentricity, the bearing must bear the overturning force,It means partial load. The eccentricity does great harm to the bearingSelf aligning refers to the function of the bearings, bearing with self-aligning function, such as self-aligning ball bearings, spherical roller bearing.Their self-aligning roller bearing angle is limited, is not higher than 0.5 degreesI hope you will accept it
The installation of spherical roller bearings have two raceways in the inner and outer ring raceways between spherical assembly, a drum shaped roller bearings. The center of curvature of the raceway of the outer race is consistent with the center of the bearing, so it has the same self-aligning function as the self-aligning ball bearing. When the axle and shell are bent, the axial load in two directions can be automatically adjusted. Radial load capacity, suitable for heavy load and impact load. Inner diameter is tapered bore bearings can be installed directly. Or the use of tight sets, the demolition cylinder installed on the cylindrical shaft. The cage uses a steel plate holder, a polyamide forming cage and a copper alloy car holder. For self-aligning bearings, the use of an intermediate mounting ring prevents the outer ring from tilting and rotating when the axle bearing is loaded into the shaft bore of the housing. It should be borne in mind that some of the self-aligning ball bearings protrude from the side of the bearing, so the middle ring should be recessed to prevent damage to the ball. A large number of bearings are generally installed by mechanical or hydraulic pressing. For separable bearings, the inner and outer rings can be installed separately, thus simplifying the installation process, especially when the inner and outer rings need interference fit.
